CHLORIDE BASED ACCELERATING ADMIXTURE FOR CONCRETE

Specco A-10C is a liquid calcium chloride solution that is added to concrete mixes, to accelerate the normal set-time and to lower the freezing point of the mix. Additionally, A-10 increases the ultimate strength and improves the workability of the batch materials.

BENEFITS:

Reduces set times.

Improves workability.

Increases strength development in portland cement mixes at crucial early stages.

Can be used as a deicing solution for driveways or related flatwork.

COMPOSITION: 32% calcium chloride solution

DOSAGE: A-10C Accelerator may be added to the mix in the following proportions. The Portland Cement Association recommends that calcium chloride be added at no greater than 2% of the cement weight to avoid any long term corrosion problems with reinforcement steel. Therefore, A-10C Accelerator can be added at a maximum rate of approximately 2.4 quarts per bag of cement to keep the chloride at this 2% level. However, temperatures colder than 20°F may still require higher dosages to provide adequate set as shown below.
